I am having trouble= cross compiling ros for the Gumstix (overoevm).  I am using ROS Elect= ric.  I am using a slightly custom distribution named commonos which i= s based on OpenEmbedded.  I am rather new to cross compiling, so I am unsure of the proper terminology here.

 

I am pretty sure al= l my dependencies for my target are installed.  Because I used to get = errors about not having boost and lib4cxx installed for my target, and then= I installed them and the errors went away.

<= /p>

Here is what I did.=   I created and selected new toolchain:

 

-- Family: commonos=

-- Tuple: arm-commo= nos-linux-gnueabi

-- Sysroot: /opt/co= mmonos/commonos-14_1/overoevm/arm-commonos-linux-gnueabi<= /p>

-- Install Prefix: = /opt/commonos/commonos-14_1/overoevm/arm-commonos-linux-gnueabi/usr/

-- File: /home/baxe= lrod/.ros/eros/toolchains/commonos/arm-commonos-linux-gnueabi.cmake

 

And I created and s= elected new platform:

 

-- Family: commonos=

-- Name: overo=

-- CFlags:

-- LFlags:

-- File: /home/baxe= lrod/.ros/eros/platforms/commonos/overo.cmake

 

I am not too sure a= bout all these settings.  What I do know is that if I source this file= :  “/opt/commonos/commonos-14_1/overoevm/environment-setup”= ;, I can then compile programs for my embedded target with “arm-commonos-linux-gnueabi-gcc”. 

 

Then, when I do:

rostoolchain select= commonos/arm-commonos-linux-gnueabi

rosplatform select = commonos/overo

rosprotect --unprot= ect --comms

rosprotect --pre-cl= ean --comms

 

I get this error:

…<= /span>

  /opt/commono= s/commonos-14_1/overoevm/bin/../lib/gcc/arm-commonos-linux-gnueabi/4.5.3/..= /../../../arm-commonos-linux-gnueabi/bin/ld: skipping incompatible /opt/ros= /electric/ros/tools/rospack/lib/librospack.so when searching for -lrospack

  collect2: ld= returned 1 exit status

[ rosmake ] Cleaned= 12 packages.          &n= bsp;            = ;            &n= bsp;            &nbs= p;            &= nbsp;           &nbs= p;            &= nbsp;           &nbs= p;            &= nbsp;           &nbs= p;           

[ rosmake ] Built 7= packages with 1 failures. 

 

So I guess librospa= ck.so is not being compiled with the embedded target compiler?

 

Also, FYI, the tool= chain bridge wiki page has some lines like this:

roscd eros_apr; mak= e; make install

 

which succeeds.&nbs= p; However, I think it only succeeds because the package is not cleaned fir= st.  If I simply:

rosmake --pre-clean= eros_apr

 

I then get this err= or:

/usr/lib/libuuid.so= : could not read symbols: File in wrong format

 

Which is strange be= cause if I do:

locate uuid

 

I see that I have t= his library for both my native and embedded target environments:=

/lib/libuuid.so.1

/lib/libuuid.so.1.3= .0

/opt/commonos/commo= nos-14_1/overoevm/arm-commonos-linux-gnueabi/usr/lib/libuuid.la<= /span>

/opt/commonos/commo= nos-14_1/overoevm/arm-commonos-linux-gnueabi/usr/lib/libuuid.so<= /span>

/opt/commonos/commo= nos-14_1/overoevm/arm-commonos-linux-gnueabi/usr/lib/libuuid.so.1

/opt/commonos/commo= nos-14_1/overoevm/arm-commonos-linux-gnueabi/usr/lib/libuuid.so.1.3.0<= /o:p>

 

Any help?  Tha= nks in advance.
